A ground wire connection nut ( 14 A) and a cover-fixing nut ( 14 B) are molded in a case ( 12 ) at positions shifted in an axial direction thereof. Caps ( 17 ) are mounted on each nut ( 14 A, 14 B). First and second receiving surfaces ( 33 A, 33 B) are formed on each cap ( 17 ) at positions shifted in the axial direction. First and second positioning portions ( 30 A, 30 B) are formed in a die ( 36 ) and contact the first and second receiving surfaces ( 33 A, 33 B) respectively. An axial length of each positioning portion ( 30 ) is set according to the specified position of each nut ( 14 A, 14 B). The same kind of the caps ( 17 ) can be used commonly for the nuts ( 14 A, 14 B) to reduce the manufacturing cost.
